A fitting (21) for providing a substantially fluid-tight seal between an opening in a chamber wall (10) and a pipe (4) passing through said opening, said fitting comprising: (i) a tubular sleeve (22) adapted to pass through the opening in the chamber wall (10) and further adapted to allow the pipe (4) to pass through the sleeve (22); (ii) a flange (24), extending radially outwardly from the sleeve (22), a first surface (26) of the flange being configured to contact the chamber wall (10) around substantially the whole circumference of the opening and over substantially the whole first surface (26) of the flange; (iii) a first energy transfer means (28) incorporated in the flange (24) and situated at or near the first surface (26) of the flange, said energy transfer means (28) being adapted to heat the first surface (26) of the flange in order to form a substantially fluid tight seal between the wall (10) and the flange (24); characterised in that at least part of the tubular sleeve (22) is tight sliding fit with the pipe (4) passing through it and in that part of the sleeve (22) incorporates a second energy transfer means (38) adapted to form a substantially fluid tight seal between the sleeve (22) and the pipe (4). A method of forming such a seal using said fitting (21) is also provided.
